I MOLDING AND CASTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 745,649, dated December1, 1903.

Application tiled June 7, 1902. Serial No. 110,672, '(No model.)

To 0,51 whomit may concern:

Be it known that I, JAMES R. MOWANE, a

burg, in the county of Campbell and State of Virginia, have invented anew. and useful Molding and GastingApparatus, of which the following isa specification.

In a patent granted to me' on September 10,

trated and described novel apparatus for molding and cast iug metaLwhichconsists,substantially, in spaced mold-receiving benches forming an.alley therebetween in which is movably mounted a table carrying suitablemolding apparatus. The claims in the afore said patent cover only theconstruction of the supports for the molds shown in that 'in stance aspeculiarly-constructed benches, and the claims upon the remainder of theapparatus were required to be divided out.

The present invention relates to thesame class of apparatus, and whilethe claims cover, broadly, certain combinations required to beeliminated in the former application, and therefore include thestructure as a whole shown in said Patent No. 682,484, there are certainimprovements embodied in this present structure that are of the greatestimportance. In the apparatus illustrated in said patent the movablemolding-table was supported on legs, upon the lower ends of which werejonrnaled wheelsthat rested upon the molding-floor. These floors areoften uneven, and the sand piled thereon was continually blocking thewheels, thereby stalling the table or throwing it out of'its' course, sothat it would come into contact with the benches. This objectionablefeature has been overcome by supporting the table or molding apparatusso that the sand will not interfere with its progress, and it willnecessarily remain iuits proper relation with respect to the mold-sup-Heretofore it has been the custom to makea single mold at the time, andthis could readily be transferred from themolding apparatus to themold-support by hand; but I- have devised means for making a pluralityof molds simultaneously. This necessitates larger flasks, and the bodyof sand being greater the molds are of course much heavier.

Another feature of the invention, therefore,

butinsuring more expeditious as well as more accurate and carefulhandling. The apparatus is of course useful for single molds, es-

pecially those of larger sizes, and the invention is capable of use inconnection with flasks and molds of various sorts, though primarilyintended, as in the patented structure, for use .in the manufactureofplow-points.

The preferred embodiment of this invention is fully illustrated intheaccompanying drawings and described in thefollowingspecification, thoughit will be readily apparent upon an inspection of the claims heretoappended that the invention is open to various changes and wide;modifications from the structureishown' and described.

In' the drawings, Figure 1 is a side elevation of the improvedapparatus. Fig. 2 is an end elevation of the molding-table. Fig. 3 isatop plan view of the same. Fig. 4 is a plan view of the apparatus.

Similar numerals of reference designate corresponding parts inall thefigures of the drawings.

In the embodiment of the invention the molding-table is designated as awhole by the reference-numeral 10, substantiall y the same moldreceiving or casting'benches 11 being employed in connection therewith.These benches consist of standards 12, secured rigidly in an uprightposition by means of sleepers 13, firmly embedded in the floor and inthis instance cast integral with the standards. Projecting from theupper ends of said standards are the outwardly extending cross-arms 14,that form portions of the open frames of the benches. Connecting theupper ends of the standards 12'are horizontallyneath the benches thereare preferably arranged inclined platforms 18, that extend the entirelengths of the same and are designed to throw the sand and castingsforward toward the alley formed between the spaced adjacent benches, aswill be readily understood. The outstanding cross-arms 14 are providedin their outer ends with seats 19, and tracks 20, secured to theadjacent edges of the benches, are fitted in these seats, the tracksextending the entire lengths of the benches and constituting thesupports upon which the table runs.

The table 10 in the present instance is constructed of bars 21 and 22,secured together to form a rectangular open frame, the bars 22projecting beyond the table at one side, as clearly shown at 23.Extending across this table are shafts 24, journaled in bearings 25,

. secured to the upper faces of the bars 22,

said shafts carrying on their other projecting ends suitable flangedwheels 26, which rest upon the tracks 20. Supported upon the table 10 isany suitable molding apparatus, shown in the present construction asmatches 27, designed to make a plurality of molds simultaneously. Ifdesired, the apparatus described in either of my former patents grantedSeptember 10, 1901, and numbered 682,485 and 682,486, may be employed,or other apparatus of any known or desired construction may be used. Itwill be apparent, however, that molds made upon the apparatus shown willbe of considerable weight and not readily transferred manually.

'In order, therefore, that such molds may be expeditiously handled,mechanical means are employed, which are preferably, though notnecessarily, constructed as follows: Spaced standards 28 are secured tothe rearwardlyprojecting portions 23 of the frame-bars, these standardsbeing made rigid by suitable braces, as 29, and tie-bolts 30. Attachedto the upper ends of the standards are horizontally-disposed brackets31, that project over the molding apparatus and have in their projectingends seats, as 32. Secured to the free ends of the brackets 31 is atrack 33, fitting in the seats 32 and extending across the table andover the mold-receiving or casting benches 11, this track being locateddirectly over the centers of the matches, as clearly shown in Fig. 3.

Mounted upon the above-described track is the mold-transferringmechanism, consisting of a hanger 34, supported by wheels 35,which restupon the track, said hanger having hori zontally-disposedantifriction-rollers 36, that bear against the side of the track, and adepending hook 37, which is offset, so as to be located directly beneaththe track, as shown in Fig. 2. From this hanger is suspended hoistingmechanism, which may be of any desired construction, though preferablyin the form of an ordinary air-hoist comprising a cylinder 38, having aneye 39 at its upper end, in which the hook is engaged, and an ordinaryplunger-rod 40, extending through its lower end. An air-supply pipe 41leads to the cylinder from any suitable source of compressed air, theopening through said pipe being controlled bya valve 42, havingoperating means, shown in the form of an endless chain 43, extendingabout a suitable pulley 44, attached to the projecting end of thevalvestem. A flask-engaging bail 45 is attached to the projecting end ofthe piston-rod 40 and is provided with terminal hooks 46,arranged toengage pintles, as 47, arranged upon opposite portions of theflask-sections. At the ends of the track 33 are located stop-pins 48,which engage the hanger to limit the movement thereof, one of these pinsbeing illustrated in Fig. 1 of the drawings.

The manner of using the apparatus is substantially the same as thatdescribed in my former patent, numbered 682,484. The flaskseotions arefirst placed upon the matches located upon the molding-table, and thesand is shoveled from the floorinto the flasks and rammed up, thusforming the two sections of the mold. The hoisting mechanism is thenlowered and the bail is engaged with the drag, which is then elevatedand the carrier moved over one of the mold receiving or casting benches.The drag is then revolved to bring the mold-face uppermost,after whichit is lowered to its position upon the moldsupporting platform 16. Thecarrier is then moved back, and the cope is in like manner raised andtransported to its proper position upon the track, thus forming thecomplete mold and placing it in proper position for the castingoperation. The empty flask is then taken from the opposite correspondingplatform of the opposite bench, and the mold is in like manner madetherein. After these two molds have been completed the molding apparatusis moved to the next set of flasks, and so on until the entire fioorhasbeen completed, after which the usual casting opera tion takes place,the molds are broken, and the castings removed. The advantages for thisgeneral combination have been fully set forth in the prior patent; butoutside of these the improvements have particular advantages of theirown. In the first place, the table'being supported above the floor iscompletely out of the Way of the sand, which will therefore notinterfere with it. Moreover, this table now runs upon tracks whichmaintain it in its proper position and insure its easy movement. Furtherthan this, the mechanical means fortransferring the flasks and molds isexceedingly useful, as it saves much time'and labor, and its actionbeing steady and accurate there is a less percentage of broken orinjured molds.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe IIC spirit or sacrificing'any of the advantages of the invention.
